Patent DE-4208732-A1 (DE)
Inventor: ERHARDT URSULA DR
IPC: B01L3/00
Filed: 1992-03-18
Abstract: The present invention concerns a one-way reaction vessel, open at both ends, for solid phase immunological analysis, with at least one immunologically reactive constituent applied onto a substrate with an active or activated surface. Said reactive constituent has a load density such that the constituent to be determined binds quantitatively (bonding equilibrium) to the reactive constituent before the flowing liquid leaves the substrate; the volume of the substrate bed is up to 600  mu l, and the flow speed of the liquid from the substrate bed is determined accordingly. The one-way reaction vessel can be used to measure constituents which can be determined on the basis of immune reactions.

Patent DE-4212248-A1 (DE)
Inventor: GITTNER FRANZ
IPC: B29C49/64
Filed: 1992-04-11
Abstract: The invention relates to the heating of cold, injection moulded preforms (parisons) which are heated to blow moulding temperature in sections in a heating zone (24) by infrared radiators, by the so-called "reheat process", on a belt, rotating about their axis, and for the distribution of the heat over their cross-section by means of smoothing sections between the radiators and are then fed to a hollow-article blow moulding device. For processing crystalline polymers, in particular polypropylene, it is proposed that before the preforms pass into the heating zone (24), they pass through a preliminary zone (7) on which they are already kept rotating, that in the heating zone they are simultaneously heated on one side and cooled on the opposite side and that following the heating zone (24) they pass through a hot-air conditioning and protecting zone (25) in a virtually closed system (20), before they are fed to a blow moulding device.

Title: Tree and vine trimmer - is power driven with hydraulically operated piston cutter and electrically activated switch in neck of handle
Inventor: HAMMER FRANZ
IPC: A01G3/033
Filed: 1992-04-16
Abstract: The cylinder (13) is connected by a hydraulic line (5) to a pressure reservoir (2) which is held in constant pressure by an aggregate (3), and a switch (9) in the hydraulic line relieves the pressure by closing the connection between the reservoir and the line. Electric cables (6, 7) connect the switch to an activator button (15). The cutting surface of the cutter (11) is at right angles to the axis through the handle (12). The cutter is forced upwards towards the fixed jaw (10) by hydraulic pressure from the cylinder working against the spring (14). After a cutting process the pressure in the hydraulic line is released by a valve so that the cylinder recoils under spring pressure, and with it the cutter retracts to the open position. USE/ADVANTAGE - Tree and vine trimmer is handy to use with max. power assistance.

Title: Method and installation for the manufacture of particle boards (chip boards)
Inventor: BIELFELD FRIEDRICH BERND
IPC: B30B5/06
Filed: 1993-01-21
Abstract: The invention relates to a method for the continuous manufacture of particle boards, fibreboards, plastics and plywood boards using a continuously operating press having flexible, endless steel belts which transmit the pressing pressure and also draw the material to be pressed through the press and which are guided via driving drums and deflecting drums around the pressing table and pressing ram and are supported with adjustable pressing gap, via live rolling bars guided with their axes transverse to the belt running direction, against abutments of pressing table and pressing ram, and the compression angle of the entry gap being variable by means of an adjusting device.

Patent DE-4310009-A1 (DE)
Inventor: KRUEGER JOERG DR
IPC: F22B37/02
Filed: 1993-03-27
Abstract: The invention relates to a method for generating steam in a district heating power station by evaporating feed water in a combustion boiler, feeding back the heating steam and condensing it after heat dissipation and reutilising it as feed water. A fraction of the heat content of the flue gases of the combustion boiler is fed via an economiser to the feed water, and the flue gases are guided via a flue gas cleaning system. The invention also relates to an installation for carrying out the method. The object of the invention is to develop a method and an installation which render it possible to ensure effective steam generation in conjunction with maximum heat utilisation by the installed heating surfaces, and at the same time to ensure preheating of the exhaust air and of the flue gas during start up and shut down operations. The object is achieved by means of a method for generating steam in a district heating power station and an installation for carrying out this method. In this case, before entering an economiser (2) the feed water is set up in terms of quantity and temperature in a manner independent of a feed water requirement of the combustion boiler (1), but dependent on the temperature regime in the economiser (2). In the case in which the temperature on the surface of the economiser (2) on the exhaust gas side is below the dew point of the exhaust gas, the temperature of the feed water and the feed water throughput are set by the economiser (2) in such a way that a temperature is set up on the surface of the economiser (2) on the exhaust gas side which is above the dew point. If the temperature of the feed water in the economiser (2) has reached the boiling range, in accordance with the invention the feed water throughput through the economiser (2) is increased above the quantity necessary for the required steam power, while a proportion of the feed water reemerging from the economiser (2) is fed back, cooled and recirculated before entering a drum (24) of the combustion boiler (1). <IMAGE>

Patent DE-4330062-A1 (DE)
Inventor: KLEINE HOMANN WALTER
IPC: B29K67/00
Filed: 1993-09-06
Abstract: The object is to prepare a high-molecular-weight polyester in such a way that it is advantageously possible to produce even relatively small amounts of very high molecular weight in a very short time. This is achieved by the preparation of a polyester having an alkenediol content by continuing the polycondensation step to a viscosity number of from 50 to 140 cm<3>/g and subsequently subjecting the resultant polyester to solid phase postcondensation until the requisite viscosity number has been reached. The novel process enables high-molecular-weight polyesters having the desired property profile to be obtained.
